标准模型之外的几种情况预测，由于运动学约束、守恒的量子数或弱耦合，重的长寿命粒子。这些粒子可能是通过异常能量损失、出现或消失的轨迹、移动的顶点、轻子喷流信号、长时间飞行或晚期量热能量沉积来识别的。这篇文章总结了ATLAS探测器使用质量中心能量为8TeV的PP碰撞数据搜索重的长寿命粒子的最新结果。
Several scenarios beyond the Standard Model predict heavy long-lived particles as a result of a kinematic constraint, a conserved quantum number or a weak coupling. Such particles are possibly identified based on the detection through abnormal energy losses, appearing or disappearing tracks, displaced vertices, lepton-jet signatures, long time-of-flight or late calorimetric energy deposits. This contribution summarizes recent results of searches for heavy long-lived particles with the ATLAS detector using pp collision data at a center of mass energy of 8 TeV.
